[0002] Dentures are commonly referred to as "false teeth." Just like we refer to "artificial legs" and "artificial limbs" as "prosthetic limbs," "dentures" refer to teeth that fulfill a "duty" for humans.

DETAILED DESCRIPTION

[0048] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0049] See also Figures 1 to 12 , the present invention provides a technical solution: Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, it includes a clamping mechanism 2 for limiting and fixing the finished denture, and a fixing platform 1 is provided on the outside of the clamping mechanism 2;

[0050] The measuring mechanism 3 is used for measuring the top contour of the denture and the tooth spacing. The measuring mechanism 3 is arranged on the top of the fixing platform 1.

[0051] The clamping mechanism 2 includes a limiting folding plate 21, which is fixedly connected to the outer side of the fixed platform 1. The outer side of the limiting folding plate 21 is sleeved with an adjusting rod 22. The outer end face of the adjusting rod 22 is fixedly connected to a first arc-shaped rail 23. The inner side of the first arc-shaped rail 23 is adapted to slide with an inner moving block 24. The outer side of the inner moving block 24 is fixedly connected to a connecting rod 25. The end of the connecting rod 25 away from the inner moving block 24 is fixedly connected to a positioning ring 26, wherein the positioning ring 26 is used to position the contour of a certain denture;

[0052] The inner side of the fixed table 1 is fixedly mounted with an arc-shaped table 27, and the outer side of the arc-shaped table 27 is appropriately embedded with a nesting plate 29;

[0053] A through hole 28 is formed on the outer side of the fixing table 1, and the through hole 28 is used to provide a certain placement space for the curved table 27 and to be embedded in the interior of the nesting plate 29;

[0054] The top of the nesting tray 29 is fitted with a fitting block 20;

[0055] The connecting plate 201 is used to place the finished denture and is fixedly connected to the top of the engaging block 20;

[0056] The airbag 202 is used to wrap and protect the gums and the part below the gums of the finished denture and is arranged inside the connecting plate 201;

[0057] The outer side of the arc-shaped platform 27 is fixedly connected to an outer sleeve 203, and the inner side of the outer sleeve 203 is slidably adapted to be fitted with an insert plate 204;

[0058] The insertion rod 205 is used to limit the insertion plate 204 and is fixedly connected to the insertion plate 204. The end of the insertion rod 205 away from the insertion plate 204 is plugged into the outer sleeve 203;

[0059] A compensating block 206 is fixedly connected to the outer end surface of the insertion plate 204, which is used to limit the position of the nesting plate 29. The finished denture is placed into the connecting plate 201, and then the inflated airbag 202 is placed to limit and fix the gums and the area below the gums of the denture. The teeth of the denture are exposed and not contacted or squeezed by the airbag 202. Then, the interlocking block 20 connected to the bottom of the connecting plate 201 is inserted into the nesting plate 29. The surface of the interlocking block 20 is connected to the nesting plate 29. Therefore, the interlocking block 20 and the nesting plate 29 are not simply inserted by sliding, but require a relatively large external force to squeeze and engage. After the connecting plate 201 is connected to the nesting plate 29 via the engaging block 20, the three are pushed through the through-hole 28 until the nesting plate 29 engages with the surface of the curved platform 27. Similarly, the area where the nesting plate 29 and the curved platform 27 engage has a friction bump. The insertion plate 204 is then pushed inward along the outer sleeve 203, causing the insertion rod 205 connected to the outer side of the insertion plate 204 to be inserted into the inner side of the outer sleeve 203 and engage with each other. The compensation block 206 connected to the other end of the insertion plate 204 limits the area where the nesting plate 29 and the curved platform 27 engage. The direction of movement of the nesting plate 29 is perpendicular to that of the compensation block 206. This facilitates the disassembly of the denture after measurement and provides greater stability and reduced light pollution compared to traditional hand-held positioning.

[0060] like Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, the outer side of the arc-shaped platform 27 is fixedly connected to an outer sleeve 203, and the inner side of the outer sleeve 203 is slidably adapted to be fitted with an interleaving plate 204;

[0061] The insertion rod 205 is used to limit the insertion plate 204 and is fixedly connected to the insertion plate 204. The end of the insertion rod 205 away from the insertion plate 204 is plugged into the outer sleeve 203;

[0062] The outer end surface of the interpenetrating plate 204 is fixedly connected with a compensation block 206, wherein the compensation block 206 is used to limit the position of the nested disk 29;

[0063] The bottom of the No. 1 slider 35 is fixedly connected to the No. 2 straight rail 36, and the outer side of the No. 2 straight rail 36 is fixedly installed with the No. 2 motor 37. The output end of the No. 2 motor 37 is connected to the No. 2 screw rod 38 through a coupling;

[0064] The second screw rod 38 is connected to the inside of the second straight rail 36 through a bearing, and the outer side of the second screw rod 38 is threadedly connected to the second slider 39, and the bottom of the second slider 39 is provided with a contour measurement component 30; by starting the No. 1 motor 33 and the No. 2 motor 37 respectively, the No. 1 screw rod 34 and the No. 2 screw rod 38 connected to the output ends of the two motors through couplings will both rotate, wherein the outer side of the No. 1 screw rod 34 is threadedly connected to the No. 1 slider 35, so the No. 1 slider 35 will indirectly move the contour measurement component 30 left and right, and the outer side of the No. 2 screw rod 38 is threadedly connected to the No. 2 slider 39, so the No. 2 slider 39 will move the contour measurement component 30 back and forth, and the hydraulic plate 31 needs to be started to realize the function of allowing the contour measurement component 30 to move in any direction within a limited area.

[0065] The contour measurement assembly 30 includes a circular rail 301, a column 302 is fixedly installed at the bottom of the circular rail 301, a square block 303 is fixedly connected to the bottom of the column 302, an optical sensor 304 is fixedly connected to the bottom of the square block 303, and a positioning rod 305 is fixedly connected to the bottom of the optical sensor 304, wherein the positioning rod 305 is adapted to the inner wall of the positioning ring 26; the center of the bottom of the circular rail 301 is fixedly connected to the column 302, and the bottom of the column 302 is connected to the optical sensor 304 through the square block 303, and the optical sensor 304 will perform real-time contour measurement processing on the tooth groove at the top of the finished denture, and before that, it is necessary to push the adjustment rod 22 inward along the limiting folding plate 21 so that the No. 1 arc rail 23 connected to the outer end of the adjustment rod 22 will be in the connection plate 20 1 is located directly above the hollow cavity, while the finished denture, restrained by the airbag 202, is placed inside the hollow cavity. The first curved rail 23 is fitted with an inward movement block 24, the other end of which is connected to a positioning ring 26 via a connecting rod 25. An external computer operates two motors, causing them to indirectly drive a positioning rod 305 fixed to the bottom of the optical sensor 304 to rotate along the inner wall of the positioning ring 26. The positioning rod 305 is in close contact with the positioning ring 26, and the positioning ring 26 serves to further expand the contour range of the denture to be measured, thereby facilitating the optical sensor 304's expanded measurement range and preventing the computer from having difficulty accurately determining the denture's boundaries during image recognition and processing, which could affect the accuracy of distance measurement. The inner diameter of the positioning ring 26 is slightly larger than the cross-section of the largest tooth in the denture.

[0066] The bottom of the circular rail 301 is slidably connected to an arc block 306, the bottom of the arc block 306 is fixedly connected to a vertical block 307, the bottom of the vertical block 307 is fixedly connected to a circular joint 308, the bottom of the circular joint 308 is rotatably connected to a rotating ball seat 309, and the interior of the rotating ball seat 309 is provided with an internal ball 300;

[0067] The bottom of the rotating ball seat 309 is provided with a bottom groove 51, and the bottom of the inner ball 300 is fixedly connected with a bottom rod 52, and the bottom rod 52 is slidably adapted to the bottom groove 51;

[0068] A wire tube 53 is fixedly connected to the bottom of the bottom rod 52. Inside the wire tube 53 is an electrical wire 55. A light 54 is mounted at the bottom end of the wire tube 53, connected to the electrical wire 55. The accuracy of the optical measurement system is affected by various factors, most of which is the stability of the light source. Therefore, the light 54 also provides a sufficient amount of light for the optical sensor 304, preventing it from measuring dark areas of the denture. Furthermore, a cover is provided around the edge of the light 54. The cover is made of frosted glass or a diffuser, which evenly scatters light across the denture surface, preventing strong reflections and effectively reducing glare.

[0069] The outer side of the arc block 306 is fixedly connected to the extension block 50, and the bottom of the extension block 50 is fixedly installed with an electric push rod 56. By starting the electric push rod 56, its bottom output end will move downward and squeeze the L-shaped rod 58 downward, wherein the part where the electric push rod 56 and the L-shaped rod 58 are squeezed is spherical. In addition, a ring sleeve 57 is fixedly connected to the outer side of the output end of the electric push rod 56. Its function is to move the remaining telescopic rods downward along with the electric push rod 56. There is only one electric push rod 56 in this device, and the rest are telescopic rods. The outer side of the output end of the electric push rod 56 is fixedly connected with a ring sleeve 57, and the bottom extrusion of the electric push rod 56 is adapted to be fitted with an L-shaped rod 58, which is fixedly connected to the bottom rod 52, and the top of the L-shaped rod 58 is fixedly connected with a reset spring bar 59, and the end of the reset spring bar 59 away from the L-shaped rod 58 is fixedly connected to the vertical block 307. Then the L-shaped rod 58 squeezed by the electric push rod 56 will stretch the reset spring bar 59 and tend to move downward, wherein the reset spring bar 59 has a contraction force and an elastic force, which plays a role in resetting the L-shaped rod 58, wherein the other end of the L-shaped rod 58 is connected to the bottom rod 52, and the bottom rod 52 is fixedly connected to the inside of the inner ball 300, and the inner ball 300 is slidably adapted to the inside of the rotating ball seat 309, and the bottom of the rotating ball seat 309 is provided with a bottom groove 51, wherein the function of the bottom groove 51 is to limit the five degrees of freedom of the bottom rod 52 so that it can only deflect left and right. Therefore, when the L When the contoured rod 58 is squeezed by the electric push rod 56, it causes the bottom rod 52 to deflect leftward along the bottom groove 51. The wire tube 53, fixedly connected to the bottom of the bottom rod 52, also deflects leftward with the light 54. The wire 55 serves to energize the light 54. Furthermore, the edges of the denture may have irregular shapes, reflections, or shadows. The rotating ball seat 309 is rotatably mounted within the circular socket 308, allowing the light 54 to rotate circumferentially, thereby preventing irregular shadows from the denture edges, which could cause measurement errors by the optical sensor 304. Furthermore, multiple light sources at different angles are used to simultaneously illuminate the denture. By rationally combining light from different angles, shadows and reflections created by a single light source can be eliminated, resulting in more uniform illumination of the denture surface and facilitating the optical sensor 304 to obtain complete and accurate contour information. For transparent dentures, multi-angle light sources can illuminate the interior of the denture from different directions, reducing detection errors caused by localized light obstruction or refraction.

[0070] like Figure 11 and Figure 12 As shown, a spacing measurement assembly 4 is fixedly installed on the outer side of the fixed end of the hydraulic plate 31, wherein the spacing measurement assembly 4 includes a vertical rail 41, a sliding rod 42 is adapted to slide inside the vertical rail 41, and a return spring 43 is fixedly connected to the bottom of the slide rod 42. The end of the return spring 43 away from the slide rod 42 is fixedly connected to the bottom of the inner cavity of the vertical rail 41;

[0071] One end of the slide bar 42 away from the vertical rail 41 is fixedly connected to a second curved rail 44;

[0072] The bottom of the second curved rail 44 is slidably fitted with a multi-fold plate 45, the outer side of which is fixedly mounted a distance sensor 46, and the top of which is fixedly connected to a sliding sleeve 47, wherein the sliding sleeve 47 is slidably fitted with the outer side of the second curved rail 44;

[0073] The end of the sliding sleeve 47 away from the second curved rail 44 is sheathed with an inner block 48, and the end of the inner block 48 away from the sliding sleeve 47 is fixedly connected to the square block 303. By moving the square block 303 to a position aligned with the sliding sleeve 47, and then extending the sliding sleeve 47 outward to engage with the inner block 48 fixedly connected to the outside of the square block 303, when the optical sensor 304 moves downward, the slide rod 42 moves downward along the vertical rail 41 and compresses the return spring 43, wherein the return spring 43 resets the slide rod 42. Then, the two motors are activated, causing the optical sensor 304 to rotate along the second curved rail 44. The bottom of the sliding sleeve 47 is connected to the multi-fold plate 45, so that the multi-fold plate 45 rotates around the second curved rail 44. This allows the optical sensor 304 to measure the overall contour of the finished denture while the distance sensor 46 fixedly connected to the outside of the multi-fold plate 45 simultaneously measures the distance between the teeth.

[0074] When the present invention is in use: first, the finished denture is placed in the connecting disk 201, and then the inflated air bag 202 is placed to limit and fix the gums and the part below the gums of the denture, and then the interlocking block 20 connected to the bottom of the connecting disk 201 is inserted into the nesting disk 29. When the connecting disk 201 is connected to the nesting disk 29 through the interlocking block 20, the three are passed through the through-hole 28 until the nesting disk 29 is engaged with the surface of the curved platform 27, and then the insertion plate 204 is pushed inward along the outer sleeve 203, so that the insertion rod 205 connected to the outer side of the insertion plate 204 will be inserted into the interior of the outer sleeve 203 and fit each other, and the compensation block 206 connected to the other end of the insertion plate 204 will limit the part where the nesting disk 29 and the curved platform 27 are engaged, so as to facilitate the disassembly of the measured denture.

[0075] By starting the No. 1 motor 33 and the No. 2 motor 37 respectively, the No. 1 screw rod 34 and the No. 2 screw rod 38 connected to the output ends of the two motors through couplings will both rotate. The outer thread of the No. 1 screw rod 34 is connected to the No. 1 slider 35, so the No. 1 slider 35 will indirectly move the contour measurement component 30 left and right. In addition, the outer thread of the No. 2 screw rod 38 is connected to the No. 2 slider 39, so the No. 2 slider 39 will move the contour measurement component 30 back and forth, so that the contour measurement component 30 can move in any direction within a limited area. The center of the bottom of the circular rail 301 is fixedly connected to a column 302, and the bottom of the column 302 is connected to an optical sensor 304 through a square block 303. The optical sensor 304 will perform real-time contour measurement of the tooth groove at the top of the finished denture. Before that, it is necessary to push the adjustment rod 22 inward along the limiting folding plate 21 so that the No. 1 arc rail 23 connected to the outer end of the adjustment rod 22 will be directly above the hollow cavity of the connecting disk 201, and the finished denture limited by the airbag 202 is placed inside the hollow cavity. The internal sliding adapter of the No. 1 arc rail 23 is equipped with an inward moving block 24, and the other end of the inward moving block 24 is connected to a positioning ring 26 through a connecting rod 25. Therefore, the two motors are calculated by an external computer, causing the two motors to indirectly drive the positioning rod 305 fixedly connected to the bottom of the optical sensor 304 to rotate along the inner wall of the positioning ring 26, wherein the positioning rod 305 is in contact with the positioning ring 26, so that the optical sensor 304 can expand the measurement range.

[0076] By starting the electric push rod 56, its bottom output end will move downward and squeeze the L-shaped rod 58 downward. The part where the electric push rod 56 and the L-shaped rod 58 are squeezed is spherical. In addition, the ring sleeve 57 fixedly connected to the outer side of the output end of the electric push rod 56 is used to move the remaining telescopic rods downward along with the electric push rod 56. There is only one electric push rod 56 in the device, and the rest are telescopic rods. Then, the L-shaped rod 58 squeezed by the electric push rod 56 will stretch the reset spring bar 59 and tend to move downward, wherein the other end of the L-shaped rod 58 is connected to the bottom rod 52, and the bottom rod 52 is fixedly connected to the inside of the internal ball 300. In addition, the internal ball 300 is slidably adapted inside the rotating ball seat 309, and the bottom of the rotating ball seat 309 is provided with a bottom groove 51. Therefore, when the L-shaped rod 58 is squeezed by the electric push rod 56, it will move to the left along the bottom groove 51 with the bottom rod 52, and the wire tube 53 fixedly connected to the bottom of the bottom rod 52 will also move to the left with the light 54. In addition, the edge of the denture may have irregular shapes, reflections or shadows, etc., wherein the rotating ball seat 309 is rotatably installed inside the circular seat 308, so the light 54 can be deflected circumferentially.

[0077] By moving the square block 303 to a position flush with the sliding sleeve 47, and then extending the sliding sleeve 47 outward and engaging with the embedded block 48 fixedly connected to the outer side of the square block 303, when the optical sensor 304 moves downward, the slide bar 42 will move downward along the vertical rail 41 and compress the return spring 43, wherein the return spring 43 plays a role in resetting the slide bar 42, and then start the two motors to make the optical sensor 304 rotate along the second arc rail 44, wherein the bottom of the sliding sleeve 47 is connected to the multi-fold plate 45, so the multi-fold plate 45 will rotate around the second arc rail 44, so that the optical sensor 304 measures the overall contour of the finished denture while the distance sensor 46 fixedly connected to the outer side of the multi-fold plate 45 will synchronously measure the distance between the teeth.

[0078] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Various changes made by ordinary technicians in this field based on the above concepts without creative work fall within the scope of protection of the present invention.
